ANIMAL-SHEARS.

SPECIFICATION forming part of Letters Patent No. 233,575, dated October 19, 1880.

Application filed July 27, 1880. (No model.)

To all whom it may concern -Be it known that I, JOSEPH B. SWEZEY, of East Patchogue, in the county of Suffolk, and State of New York, have invented certain new and useful Improvements in Sheep-Shearing Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in thea-rt to which itappertains to make and use the same, reference heilig' had to the accompanyingdrawings, which form a part of this specification, and in which- Figure l is a perspective view of my improved sheep-shearing machine, a part of the box or casing being broken away to show the operating parts. Fig. 2 is a central longitudinal section; Fig. 3, a plan of the stationary nger-plate which operates in conjunction with the cutter-wheel; and Figa-1 is asectional View on line :rx of Fig. l.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to machines for shearing sheep; and it consists in the construction and combination of parts of a machine of that class, as hereinafter described, and particularly pointed out in the claim.

In the annexed drawings, A represents the base-plate of my machine, bolted to or made in one piece with which is the semicircular iinger-plate B, and also the handle C, which is so placed upon one side of the base-plate A that the parts of the machine on both sides thereof shall be equally balanced. Upon the base-plate is mounted a sheet-metal box, D, which incloses the operating parts and prevents dust or particles of wool from entering into and choking up the machinery.

E is an upright shaft journaled within box D, with its bearings in the base-plate A and in the roof of the box. Upon the lower end of this shaft is keyed the cutter-wheel F, and also a bevel-pinion, G, which meshes with a bevel-pinion, H, keyed upon the end of the drive-shaft I, which has its bearings at one end in a cross-bar, K, that is hinged at one end, at k, in one ofthe sidesl of box D, and projects out through a slot 1n the opposite side, forming a projecting thumb-piece or button, l, below which, inside of the casing D, 1s

Vhereinafter set forth.

arranged a spiral spring, O, for the purpose The other end of shaft I has its bearings in one of the end plates ot' box D, and is provided on its projecting end with a pinion, L, which meshes with the internal-gear wheel M, which is journaled upon a stud projecting from the end plate of the box and operated by a crank or handle, N.

From the foregoing description, taken in connection with the drawings, the operation of my machine will readily be understood. The operator, holding the machine by its handle O in the left hand, with the thumb pressing against the projecting piece or button lot' bar K, turns the crank'with his right, thereby operating shafts E I and rotating the cutter-wheel, a segment of which projects out through a slot in thefront end of box D, which said slot has a. selnicircular guide-plate, d, between which and the finger-plate B the cutter-wheel works. By letting go of the thumbpiece l spring O will lift the hinged cross-bar K, and with it shaft I, thus bringing pinions H G out of gear and stopping the operation ot' the cutter-wheel. By this arrangement the shearing may be gaged with perfect accuracy, so as to cut the iieece evenly and smoothly.

If desired, the box D may be provided with a hinged top, through which the several operating parts may be cleaned and oiled as occasion requires.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- A sheep-shearing machine composed of the base-plate A, Ahaving handle O and fingerplate B, cutter-wheel F, mounted upon the vertical drive-shaft E, having bevel-pinion G, drive-shaft I, having pinions H L, and drivewheel M, having crank N, the several parts E G I H being inclosed within the box or casing D, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

JOSEPH B. SWEZEY.
